Questions
How big is the EByte E73 PCB?
It measures 21.6 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EByte E73 use?
39 parts, built around the CH340C, E73-2G4M04S1B, AP2112K-3.3 and TP4056. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the EByte E73 KiCad files?
From the jpconstantineau/NRF52-Board repository on GitHub, at the commit this page was made from: the board is BlueMicro2.1a/EByte_E73.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EByte E73 design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
